CVE-2026-49200Network attack vector

Unauthenticated credential disclosure via web-accessible firmware log

Published May 29, 2026 · Updated May 29, 2026

Information disclosure in Acer Wave 7 firmware T7c_GBL_1.01.000055 and earlier allows remote attackers to obtain login credentials. The web interface serves acer_cgi.log without authentication even though the file records cleartext credentials for web administration and Telnet. Network reachability to the management interface is sufficient to retrieve credentials that permit unauthorized router access.
